Application mea February 3,1922. serial No. 533,743.

To all whom t may concern:

rBe it known that I, JOHN J'. REINHOLD, a citizen of the United States, and a resident of Marietta, county o-f Lancaster, State of Pennsylvania, have invented certain new and useful Improvements in Electric Fans, of which the following is a specification.

VThis invention relates to electric fans in which the air is directed through a circular 3U path, principally for the purpose of obtaining a greater distribution of the air than that obtained when the axis of the fan is held stationary, or when the fan ismerely oscillated laterally `in the usual manner.

The object of this invention is to provide a simple and compact arrangement for imparting a circulatory Vmotion to a power transmitting or producing device, for instance an electric motor as described in the following specification, and utilizing the power transmitted or produced by said device for operating said arrangement.

This invention will be more fully understood from the following description, taken in connection with the accompanying drawing, in which similar numerals refer to similar parts throughout the several views.

Fig. 1, represents a practical embodiment of my invention; certain portions of which are shown in sectional view.

Fig. 2, is a sectional view of Fig. 1, taken on line 2 2.

With reference to the drawing, 3 represents an electric motor which carries the fan 4. The motor is carried by the base 9 through a fork shaped bracket 5. The motor is provided with two pivot pins 6 (one only being shown in the drawing) upon which the motor may rock as indicated by the arrow 7. The bracket 5 is pro-vided with a stem 8 the same being adapted to freely turn in the base 9; this permits free lateral movement of the motor on a vertical axis passing through said stem. The set collar 10 should be fixed to the stem 8 through a set screw, or otherwise, to prevent the bracket 5 from separating from the base 9, however it must not interfere with free rocking movement ofthe bracket relative to the base.

A bracket forms part of the motor casing and carries a stud 24. An internal worm gear 23 is free to rotate on the stud 24 and carries a pin 12,v thereby forming a cra-nk element. A bracket 14 is fixed to the base 9 through the screws 15; the upper end being adapted to form a bearing for the pin 12.

It is apparent that since the bracket 14 is xed to the base 9 and thereby held stationary, the pin 12 is also held stationary, or in other words, held against all movement other than a rotating movement upon its own axis; therefore if by any means efforts are applied to rotate the gear 23 on the stud f 24, this gear will in fact rotate around the axis of the pin 12 with the result that the stud 24 is caused to move through a circular path around the axis of the pin 12. Since the stud 24 is fixed to the bracket 25 which forms part of the motor casing, then this end 11 of the motor is also moved through a circular path around the axis of the pin 12. It is to be observed that the y.PATENT f orifice? motor is free to respond to any efforts to move the same in this fashion, because it is free to rock on a vertical axis ruiming through the stem 8, and also on a horizontal axis running thro-ugh the point pin 6.

As a transmission means for rotating the gear 23 from the energy supplied by the motor, I provide a worm thread 17 on the end of the armature shaft 16. A shaft 19 is carried by the housing 21 and may be held against lengthwise movement by slightly riveting the ends 20. The worm wheel 22 and worm gear 18 comprise one unit which is free to rotate on the shaft 19. The worm gear 18 is adapted to mesh with the worm thread 17, and the worm wheel 22 with. the i internal worm gear 23. When the armature shaft 16 rotates it drives the worm gear 18, this `of course causes the worm wheel 22 to rotate which finally drives the worm gear 23.

From the foregoing description it may be seen that while the motor is operating to rotate the fan it at the same time actua-tes the crank element to effect a circulatorious motion to the motor, with the result that the air passing through the fan is directed through a circular path.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:

1. In an electric fan, comprising a motor, a fan driven by said motor, a base for carrying the motor, means whereby said motor may turn on a vertical axis and also4 on a horizontal axis, a crank element adapted to Carbostyril derivative or a pharmaceutically acceptable (R6)m acid addition salt thereof, having excellent platelate aggregation inhibitory effect, calcium antagonism, hy-

potensive effect and phosphodiesterase inhibitory effect are useful as prophylactic or treating agents for throm- R7 bosis, circulation improving agents for coronary blood flow such as coronary vasodilators, hypotensive agents and phosphodiesterase inhibitors. Furthermore, the carbostyril derivatives are weak in heart rate increasing activity and also in cardiac muscle contraction iiicreasing activity, and the carbostyril derivatives are useful Carbostyril derivative or a pharmaceutically acceptable PATENT AND TRADEMARK OFFICE O N (0d-m40
